A watchdog group is escalating its battle with the Justice Department over the FBI’s refusal to turn over files on Ashli Babbitt, the United States Air Force veteran shot and killed during the Jan. 6, 2021, Capitol riot over the certification of President Joe Biden’s victory over former President Donald Trump.

Judicial Watch, claiming a “cover-up,” on Friday filed a suit in federal court claiming that the FBI has twice refused to comply with Freedom of Information Act demands for any files it has on Babbitt and her husband Aaron.

The FOIA lawsuit was filed with the U.S. District Court for the Southern District of California.

Judicial Watch is working with Aaron Babbitt, who is the executor of his wife’s estate, to get all the information the government has on the duo and its reports of her shooting death by then-U.S. Capitol Police Lt. Michael Byrd as she attempted to enter the House Speaker’s Lobby unarmed.

They recently joined in filing a $30 million wrongful death suit against the government in the death of the 35-year-old, the only one associated with the riots who died on Jan. 6.

“Judicial Watch and our supporters are honored to represent Ashli’s steadfast widower Aaron Babbitt and her estate in this legal action. Ashli was shot in cold blood, and the rule of law requires justice for her,” Judicial Watch President Tom Fitton said in filing the suit on Jan. 4.

In its new FOIA suit, Judicial Watch said that not only has the FBI refused its two demands for files but that the law enforcement agency has also stiff-armed the Justice Department office that advocates FOIA compliance, the Office of Information Policy.

In its four-page filing, the attorney for Aaron Babbitt and Judicial Watch said, “the FBI has failed to produce the requested records or demonstrate that the requested records are lawfully exempt from production; or notify plaintiffs of the scope of any responsive records they intend to produce or withhold and the reasons for any withholdings.”

Fitton said, “Ashli Babbit was the only homicide victim on Jan. 6, yet the FBI has been illicitly hiding its files on Ashli Babbitt from her family for a year. Why the cover-up?”

In the wrongful death suit, a new camera angle of the shooting was provided. The time-stamped video showed an unarmed Babbitt being pushed into the House Speaker’s Lobby as Byrd raises his gun. After he shot, she fell back, bleeding from the shoulder and neck.

According to the suit, “Ashli remained conscious for minutes or longer after being shot by Lt. Byrd. Ashli experienced extreme pain, suffering, mental anguish, and intense fear before slipping into pre-terminal unconsciousness. The autopsy report identified the cause of death as a ‘gunshot wound to left anterior shoulder’ with an onset interval of ‘minutes.’ The fact that Ashli was alive and conscious in extreme pain and suffering is documented in videos of the shooting.”

The suit continues, “Furthermore, nothing about the wound track described in the autopsy report would be expected to result in immediate death or instantaneous loss of consciousness, and Ashli’s lungs contained blood, further confirming that she was alive and breathing after being shot. Ashli was pronounced dead at Washington Hospital Center at 3:15 p.m. The medical examiner determined that the manner of death was homicide.”

Byrd later said he shot Babbitt as a “last resort.” He was subsequently promoted to captain.
